Just had David and his team do blown-in in our house and the service and install was the best. They were neat clean and right away notice a huge difference in our electric bill along with overhead noise from outside from airplanes....so happy with this investment to our home!
The Koala crew did a great job. The insulation job was promptly scheduled and reasonably priced. The additional insulation should reduce my electric bill. My house needed missing insulation to be reinstalled. Jeff, and the crew were professional and super nice to deal with. Thank you so very much.
Great experience! Connor showed up on time for our consultation and he was extremely personable and real knowledgeable about all of the different insulation solutions Koala has available. I thought I would drive him crazy with all my questions, but he was patient and was able to give answers that really made sense. I decided on the spray foam, and I could not be happier with the results. I feel like I live inside a giant Yeti cooler now! I expected the foam to make a difference, but I had no idea just how effective it could be. On top of controlling the temperature, the house is a lot quieter now, which I hadn't considered when I decided to go this route. Don't hesitate to have Connor and his team out to your place. My only regret is not making this decision sooner. Thanks so much guys!
Koala did two great jobs for us. Very professional, great communication and service.
Very pleased. Would recommend to anyone that needs a good company for blown in insulation. Very professional. Arrived on time. Cleaned up afterwards. Folks were courteous and answered all my questions.
The Team at Koala Insulation provided an amazing service and deal for my attic insulation job which added additional R19 to my existing attic insulation. The team was on time and got to work immediately.
LEARN ABOUT air sealing!
One of the best ways to get the biggest return on your air sealing investment is to combine it with an insulation upgrade! Learn more about types of insulation that we use in our videos below!
Why air sealing is important
Insulation alone is not going to be as effective as with combining it with air sealing. To deliver the optimal improved energy efficiency, air sealing will act as a vapor barrier and stop any air from penetrating into your home.
By sealing all gaps and holes, it creates an air barrier, blocking air from passing through walls and the ceiling into the attic or outside air in filtrating into your home.
A properly sealed home will not only stop air leakage but will also keep water out, keeping your insulation in top condition. It also contributes to increased comfort, improved indoor quality, lower utility bills and controls moisture.
Koala insulation experts offer custom solutions to provide you with the right solutions for your specific needs. We offer air sealing services along with batt, spray foam and blown-in insulation products to guard against heat loss and moisture related problems.
Cellulose consists of fibers made from recycled newspaper, cardboard, or wood and is made with or without binders. Cellulose is a very common type of blown-in insulation as it is made from recycled materials and is chemically treated to resist pests, mold, and fire. Boric acid is the primary chemical used to treat Cellulose insulation and is found naturally in seawater, fruits, and plants.
Fiberglass is made from plastic, glass, and other raw materials that are melted and spun into fibers that resemble the texture of wool. Fiberglass insulation has moisture and fire-resistant properties. Because fiberglass is made from sand and glass, it is naturally non-combustible. Fiberglass has significant recycled content with some loose-fill products containing up to 80% recycled glass.

Dense pack in Niantic
"I had a large somewhat complex blown in cellulose wall insulation project that another contractor left unfinished. Koala was able to get me on their schedule within a couple weeks and complete the full job in 2 days. Everyone was very professional and skilled and from the moment the team showed up, everyone knew what they needed to be doing to complete the project efficiently and correctly. Blown cellulose and holes in drywall make a large mess but the Koala team went so far as to wipe down floors and horizontals with a damp rag after project completion to minimize my cleanup efforts. I received quotes from 2 other contractors in the area for the same project and Koala was the only one that was reasonably priced, the other 2 wanted to charge several thousand dollars more and couldn’t commit to the same aggressive schedule."

Highly professional, great attitude and work ethic. Really went above and beyond the call of duty. I was redoing all the insulation in my entire house when they found bats in my attic. Cool, and calm, they did the best they could and went on to another area of my home. Came back another day at no extra charge and finished the job. They also never took up my offer to buy them lunch during their work.I can't recommend enough. Great work by great guys! Thank you again!
